Yes but what mistake did I make in my derivation using the bernoullis equation then?

If this formula were to be correct, if we use the liquids in the Venturimeter and the tube to be of the same density, the velocity would come out to be zero which makes no sense. I calculated the formula and got a slightly different numerator. Am I correct?

I want you to just look around you. Take the corner of your room as origin, and define the x, y and z axes. Now you are in a 3d coordinate space. Now hold one finger of your hand in a direction denoting a vector, and one finger of the other hand denoting another vector in any other random...

How exactly is momentum transferred to fields? I know electromagnetic waves carry momentum, but in this situation I don't understand what exactly is happening. Is something sort of wave being created? If yes then how to we mathematically derive the wave

Suppose a charge is moving towards another charge at rest. At a given instant of time, The electrostatic force applied by either charge on the other is same, but only one is applying magnetic force on the other. Doesn't this violate Newton's third law?

I am still in high school and I haven't studied tensors... Can you suggest me some resource to get an idea of it?

This is what I was looking for. Thank you very much!

Thanks for answering, but I know that I can resolve it into components and solve. My problem is not that I am unable to use that equation in 3D. Rather, I am just curious whether we can write that equation as an vector equation directly without resolving. Let me elaborate... v = u + at here...

We know that a = vdv/dx But is it applicable in only one dimensional components or is this actually a vector equation? If so then how do we exactly differentiate with respect to position 'vector'?

Thank you. After reading your answer I read the paragraph in the book again and now everything is clear

I don't understand this paragraph of Resnick halliday Krane where it says that if a radial component of induced electric field exists, it would mean net electric flux is not zero. I guess I am not exactly able to visualise the gaussian surface and how the flux is not zero. Please help

Oh you're right. I didn't take it into account that the value of k could be different for different masses. This makes sense, than you

That i understand but I still have a confusion. How did we calculate the value of the universal gravitational constant G? Correct me if I am wrong but isn't the procedure like: We know the force between two objects is proportional to the product of their mass and inversely proportional to the...

Why does the text saying that the Newton's framework doesn't require the two masses to be equal? If using f = ma give us inertial mass then how is f = Gm1m2/r² a different things? Isn't the law defined as the force is directionly proportional to the product of the masses and we calculated the...

Thank you, i just started electromagnetism and i got disappointed that perhaps I'm not getting proper grasp of the concepts. Thanks for clarifying the book is wrong
